WX CrA fading

Alan, thankyou for your notification. Looking back 7000d (1997) I see only 1 vis obs below the 15.0 line (around the year 2000). As we've seen with a number of other RCBs, a full blown fade can be 8 mags or so. Perhaps this has never been documented in WX CrA before. I confirm your obsn of further fading to 14.1 vis recently and will keep an (eye) on it as well. Thanks again for bringing this to our attention.
